Abstract: A communication method includes a data channel service entity that is configured to transmit real-time interaction information between a first user equipment (UE) and a second UE that are in a same call service. The communication method includes establishing a first data channel with the first UE, establishing a first video channel with the second UE; sending, to the second UE through the first video channel, first real-time interaction information sent by the first UE through the first data channel, and/or sending, to the first UE through the first data channel, second real-time interaction information sent by the second UE through the first video channel. The first data channel is used to transmit data according to Stream Control Transmission Protocol (SCTP), and the first video channel is used to transmit data according to User Datagram Protocol (UDP).

Abstract: A method includes: a network authentication server receiving a call request message from a calling device, where the call request message includes a first user identity of a calling user and a call authentication identifier; the network authentication server sending a call authentication request to an enterprise authentication server corresponding to the first user identity, where the call authentication request includes the call authentication identifier; the network authentication server receiving a call authentication success indication from the enterprise authentication server, where the call authentication success indication indicates that authentication succeeds; and the network authentication server sending target data to a called device, where the target data includes identity information of the calling user and/or information of an enterprise to which the calling user belongs.
